HIGH-ASSURANCE ENGINEERING
Systems that can't be wrong. Verified.
Then shipped.
Dquadrant is a precision engineering studio for high-assurance software — Audits, Assurance, AI Agents · Automation, and Development. Building since 2017 · Auditing since 2020.
We work like the systems we review have to be: measured, exact, unhurried by hype.
WHY DQUADRANT
Four claims a buyer can check.
We don't ask for trust. We built a record where a single flawed line moves millions and can't be undone — and it holds up to inspection.
01
Engineering high-stakes on-chain systems since 2017 — before the platform we have started on even had smart contracts.
02
Trusted development partner of Input Output since 2020, on some of the most complex protocol code in production.
03
Trusted auditing and assurance partner of Intersect MBO since 2023.
04
Appointed to the Oversight Committee for checks and balances on treasure disbursements.
WHAT WE DO
Four disciplines, one standard.
The same verification-instinct, applied statically to code and dynamically to running systems.
01 / AUDITS
Audits
Independent code and security audits of complex, adversarial systems. Where a defect is unrecoverable, we read the code the way the attacker would — then verify every finding before we close out.
Read more →02 / REVIEWS
Assurance Reviews
Structured evidence-gathering at a defined, lower level of rigor than a full audit — the right depth when you need documented confidence, not a formal verdict.
Read more →03 / AUTOMATION
AI agents · Automation
Autonomous agents built and governed to the same standard as the systems they touch — bounded permissions, auditable decision logs, fail-closed defaults. And agent-driven testing that drives a live-system at scale to find what scripted suites miss.
Read more →04 / DEVELOPMENT
Development
Smart contracts, off-chain infrastructure, and tooling around them — built to ship, and built to survive the audit that follows.
Read more →The same discipline applies wherever correctness is contractual — payments, medical, regulated data, autonomous systems.
PROOF OF EXECUTION
Six years, one standard, no rollbacks.
Since 2020 we've worked continuously alongside Input Output's engineering organization — the hardest class of change, on live systems, with no second attempt
CONTINUITY
2020 —> now
Six unbroken years as a development, audit and assurance partner to Input Output. Vendors get replaced, we didn’t. Continuity on complex protocol work is itself the reference.
LIVE NETWORK CHANGE
2 hard forks
Coordinated breaking changes shipped to a running, high-value network — no-downtime, no lost funds, no undo. The definition of a system that has to be correct at the first time.
CRYPTOGRAPHIC ASSURANCE
SECP256K1 extensions
Evidence-based verification of cryptographic curve extensions — the same primitive securing Bitcoin, Ethereum, and much of the world’s digital signatures. Getting it wrong is unrecoverable, that’s the work we do.

TRUSTED BY
“Dquadrant partners with IOLabs to audit code from multiple angles, taking on incredible complex codebases and delivering outstanding rigor under tight timelines.”
Geoff (Jeff) Watson, Director of Technology — Input Output
“I have worked with Dquadrant for over four years, across a wide range of technically demanding and often critical pieces of work. Their understanding of Cardano is exceptional, but what has consistently stood out to me is the breadth and depth of their technical expertise beyond any single technology or domain.”
Lorenzo Bruno — Product & Membership Sector Lead - Intersect MBO
